Description
I had been using the macports version of proj, but cs2cs is giving me incorrect results.
According to a FAQ I found, and also an older version that I had built:
cs2cs +proj=latlong +datum=NAD27 +to +proj=latlong +datum=NAD83 -117 30
produces: 117d0'2.901"W 30d0'0.407"N 0.000
While on the current port build I get a results of: 117dW 30dN 0.000 (which is identical to the input).
My guess is that one, or more, of the necessary proj files is missing (conus?). I did try just copying the conus file over to /opt/local/share/proj but that didn't help. I think that maybe all the projection files have to correctly be in place before building? This is a big problem because this is an important conversion tool that is giving a wrong answer rather then just giving an error.
Thanks,

If you prefer it could be a variant. Although I don't think that the optional files are really that large. So it would be great to have them work by default.
Thanks much,

Datum shifts are an optional, compile-time feature of proj.4 that requires extra downloads.
You're right that it would be useful to have it included by default. I'll see if I can work out the necessary voodoo.
